Check if the polygon is visible in the image and if the angle between the normal to the face and the line vector going from the optical center to the cog of the face is below the given threshold. To do that, the polygon is projected into the image thanks to the camera pose.

Parameters
cMo: The pose of the camera.
alpha: Maximum angle to detect if the face is visible (in rad).
modulo: Indicates if the test should also consider faces that are not oriented counter clockwise. If true, the orientation of the face is without importance.
cam: Camera parameters (intrinsics parameters)
width,height: Image size used to consider level of detail.

Return true if the polygon is visible.
